; Nature of contents: ; Literary form: Publisher: 2009Dissertation note: A total of 260 ovaries, 260 oviduct, and 130 cervices of 130 female camels including 15 female camel calves, 34 female camel heifer and 81 adult female camels were collected from the Lahore abattoir.
Biometrical values of normal ovaries, oviduct and cervices also determined. The biometrical values of both left and right ovaries comprising of length, width, thickness and weight were recorded. Statistically there was no difference in the measurements of both left and right ovaries which however, increased with the advancement of age of camel.
The mean length of the oviducts of these 3 age groups of female camels determined. There was no difference between the mean length of both left and right oviduct of same group but difference between the group and the length of the oviducts increased with the advancement of age.
The mean length of cervices and cervical annular rings of female camels of the 3 age groups were also determined. The mean length of cervices correlated well with the number of rings.
The incidence of diseased condition of ovaries and cervices in the 3 age groups were also noted which revealed that the incidence of diseased condition of ovaries in camel calves was nil and in heifer ovarian hypoplasia (2.94%) on left ovaries and follicular cyst (1.23%) in adult female camels on the left ovary.
The incidence of diseased condition of cervices in camel calves was nil, mucocervix (2.96%) in heifers and 2.46% including mucocervix (1.23%) and cervicitis (1.23%) in adult camels. The multiple diseased condition was found (1.53%) out of 130 genitalia.
The gross and histological findings of each diseased conditions were studied.
Haematological parameters i.e. Total leukocytic count and Differential leukocytic count studied in both normal and diseased conditions. The normal Total leukocytic values were higher in calf than heifer and adult. Differential leukocytic values were higher in adult. The neutrophils numbers were higher while basophils were lower. The values of Total leukocytic count and Differential leukocytic count were also increased in diseased condition.
The biometrical norms of ovary, oviduct and cervix have been established which could be used as yard stick in diagnosis of pregnancy in female camels. The study of diseased conditions of. ovary and cervices has line-lighted the type of disease and their extent in camel. The haemotological studies including Total leukocytic and Differential leukocytic count in both normal and diseased conditions will also helpful. Based on the information, prophylactic and control measure can better be formulated.

; Nature of contents: ; Literary form: Publisher: 1993Dissertation note: Ascaridia galli is the common intestinal nematode of poultry that causes severe losses in birds resulting in decreased weight gain and fall in egg production. These symptoms show that parasitic diseases are the constraints in the development of profitable poultry industry.
To find out the prevalence 300 chicken guts were obtained from different poultry meat shops in Lahore from May to August, 1993.
An overall prevalence of 60 percent was recorded in chicks. The incidence of infection was highest (73.3 percent) in the month of July and lowest (42.6 percent) in the month of May.
For conducting haematological examination one hundred and thirty-five chicks were purchased and reared under good hygienic conditions. At the age of 15 days chicks were divided into 3 groups (A, B and C). Chicks of groups A and B were infected with 50 and 100 eggs, respectively, while group C was taken as control. After 35 days of inducing experimental infection blood samples from all the three groups were taken at an interval of 5 days i.e., 35, 40 and 45 days postinfection to examine erythrocyte count, packed cell volume, haemoglobin level, total leukocyte count and differential leukocyte count.
Significantly lower values of erythrocyte count, packed cell volume and haemoglobin were estimated in infected groups A and B as compared to control group C, while higher values were obtained for heterophil, lymphocyte and eosinophil in infected chicks resulting in an overall increase in total leukocyte count. It was also estimated that A. gal/i produced no significant change in monocyte count.
Chicks from group A, B and C were weighed every week after infection to see the effect of A. gaili infection on body weight.
Results regarding body weight showed that there was significant decrease in weight in group A and B as compared to control group C and there was also significant decrease in group B as compared to group A.

Publisher: 1993Dissertation note: One hundred arid fifty samples of each coagulated and non- coagulated blood were collected from buffalo calves (100 healthy and 50 diseased buffalo calves) of 6 to 10 months of age
The samples were analysed for total serum protein, serum albumin, serum globulin and total leuckocytic count by applying Biuret method with commercial kit (Proti) using a spectrophotorneter, and standard techninques of Cole for total leuckocytic count.
The mean total serum protein values for healthy buffalo calves of 6 to 10 months of age were observed between 5.4 19 to 7.468 g/dl. A gradual increase in totalserum protein levels was observed with an increase of age. The total serum protein values for diseased buffalo calves varied as compared to healthy calves. A decrease in mean total serum protein levels. (6.189) was associated with malnutrition, diarrhoea, fever and Fasciollosis as compared to the mean total serum protein levels in healthy calves (6.404). An increase in total serum protein level (5.793 g/dl and 7.576 g/dl) were observed during 6th and 10th month of age as compared to healthy calves (5.419 g/dl and 7.468 g/dl). This increase was due to dehydration.
A gradual increase in mean serum Albumin levels 2.458 to 3.449 g/dl was observed in healthy buffalo calves of 6 to 10 months of age. A significant (P < 0.05) difference in serum albumin values was observed in all age groups both in healthy and diseased buffalo calves. A decrease in serum albumin levels (2.516) was observed In calves suffering from malnutrition, diarrhoea, fever and fasciollosis.
The mean serum globulin levels observed in healthy buffalo calves of 6-10 months of age was observed between 3.218 to 4.144 g/dl. These serum globulin levels showed a gradual increase with increase in age of buffalo calves. An increase in serum globulin level (3.898) was observed in diseased buffalo calves as compared to healthy calves in all age groups. The diseased calves were saffertig from malnutrition, diarrhoea, fever and fasciollosis. A significant (P <0.05) difference in serum globulin values was observed in age group of 6th month of age in healthy and diseased buffalo calves whereas in all other groups it was non-significant. The mean total leukocytic count hveIs observed in healthy buffalo calves of 6 to 10 months of age ranged between 8.765 to 9.655x103 microliter. A gradual increase iii mean total leukocytic count (9.26) x 103 microlitre was observed with an increase of age in healthy buffalo calves of 6 to 10 months of age. An increase in total leukocytic count level (10.966) was observed in diseased buffalo calves as compared to healthy calves in all age groups. A significant (P <0.05) increase in total leukocytic count was observed in calves suffering from diarrhoea, fever and fasciollosis.
From the above mentioned facts it was concluded that these blood parameters are important tools in investigation/diagnosis of many diseases. These parameters enable us to understand and compare the leveI of humoral and cellular defensive components in a natural farm co idition in buffalo calves of 6 to 10 months of age.

Publisher: 1998Dissertation note: The main objective of present work was to investigate the prevalence of various diseases and economic losses, resulting due to various factors among the commercial broiler farms in and around Lahore. For this purpose, oniy those farms were included, for the purpose of collection of data which had a capacity from 5000 to 2000 birds. A questionnaire was designed to collect the data from each farm that related to morbidity rates, mortality rates, vaccination, susceptible age, managemental fault, economic losses and cost analysis for various diseases. This study project was divided into two portions. During one year retrospective study (October 1996 to September, 1997) data was collected from 28 broiler farms. They had a total capacity of 118,000 birds and overall diseases mortality rate was 9.09%. Important diseases observed in this study were IBD (2.5%), 1-IPS (2.09%), earJ' chick mortality (1.85%) followed by colibacillosis (0.6%). Respire tory disease complex (0.5%), Ascites (0.47%), Coccidiosis (0.4%), Aspergillosis (0.314%) and N.D. (0.05%). Economic losses due to these diseases were calculated to be about 4.7% ed on 10 farms randomly selected out of 28 farms. Influence of season on disease was observed by Jividing a calender year into winter season (October 1996 to March 1997) and summer season (April 1997 to September 1997). Comparison of winter and summer season revealed that the incidence of IBD, Ascites, Respiratory disease complex and early chick mortality were higher in winter than summer, while incidence of hydropericardium coccidiosis and colihacillosis were higher in summer than winter. In second phase of this project, a prospective study was arraiied from January, 1998 to March, 1998 in 22 farms. During this study, 21700 birds were examined and overall 9.91% mortality rate was recorded. Important diseases observed in this prospective study were IBD (2.9%), ECM (2.25%), Respiratory disease complex (1.08%) and lIPS (1.11%) followed by colibacillosis (0.67%), ascites (0.51%), foul typhoid (0.14%), coccidiosis (0.37%), aspergillosis (0.29%), fowl cholera (0.16%) and N.D.

Publisher: 1998Dissertation note: This research project was conducted at Outdoor 1-Jospital, College of Veterinary Sciences, Lahore. Forty animals i.e. sheep and goats suffering from simple indigestion were selected, the diagnosis was based on history clinical signs and physical examination
Laboratory examination including rumen pH, serum pH, Ketone bodies estimation, protozoa motility test and cellulose digestion test were also performed to confirm the diagnosis, Animals were divided into four groups A,B,C, and D comprising 10 animals each. Animals of group A.B and, C were treated with Magnesium sulphate 50 gm. Magnesium hydro-oxide 50 gm and 1-1/2 liter normal saline once orally respectively while group D was kept as untreated control.
Before treatment, rurnen pH, values 5.702±0.195, 5.681±0.180,5.466±0.074,5.813±0.276 and cellulose digestion test time values 31.3±2.4,31.3±2.3,33.6±0.7, 30.1±3.1 hours in the four groups respectively. Minor protozoa! motility was observed alongwith no serious changes in serum pH and absence of ketone bodies in all the groups. few cases of increased rumen pH were due to ingestion of legumes or urea.
After treatment in group A protozoa motility was moderat while Rumen pH, cellulose digestion test time was 6.248±0.127 and 23.7±0.7 hours respectively. In group B which was treated with magnesium hydro-oxide normal rumen pH value was 6.981±0.034 and cellulose digestion test time 12.6±0.6 hours. In group C little protozoal movements were observed with minor improvement in rumen pH and cellulose digestion test time while in group D, the health of the animals further deteriorated with more disturbance in rumen pH and cellulose digestion test time values.
Magnesium hydro-oxide emerged as effective and economical
drug for the treatment of this condition.

Publisher: 2013Dissertation note: Functional food does not only provide nutrition but works as defense against human nutrition related diseases (Menrad et al, 2000). Global market of functional foods industry has worth at least 33 billion US$ (Hilliam, 2000). Functional foods are the foods that provide health gains and can reduce the risk of diseases beside basic nutrition, including health care of gut. The first generation of functional foods involved supplementation of calcium (Ca) and vitamins for their recognized health attributes (Saarela et al, 2002). Among these additives, probiotics and prebiotics have acquired more interest as a major group of functional food additives (Gibson and Ziemer, 1998).
GOS present in commercial milk powder has the ability to promote the growth of bifidobacterium and lactobacilli in vitro reported by the studies (Cummings et al, 2001; Cummings, 1995).The market of GOS in infant formulae milk as a food ingredient and due to its bifidogenic properties is gaining popularity (Chow, 2002). GOS are chiefly used in infant milk formula and infant foods (Crittenden and Playne, 2009). Their remarkable thermostable properties allow them to be incorporated in large variety of foods and commercial products in addition to infant foods (Yang and Silva, 1995). Recently, they have been used in beverages (fruit juices and other acid drinks), meal replacers, fermented milks, flavored milks, and confectionery products (Affertsholt-Allen, 2007).
Laboratory scale reactions for GOS synthesis were carried out by dissolving 600mM lactose solution in phosphate buffer (0.1 M, pH: 6.8) to which £]-galactosidase at varying levels was added. As indicated by studies in the literature (Kim, 1997; Barbara et al, 2006; Playne et al, 2009), high lactose concentrations facilitate transglycosylation reactions.
Milk was procured from local market and concentrated for 15 min and milk was stored at refrigeration temp for further analysis. 5ml of milk samples was taken for enzyme analysis 0£gl, 100£gl, 200£gl, 300£gl and 800£gl respectively samples was collected at 30min
_____________________________________________________________SUMMARY

Determination of Biogenic Amines (Histamine & Putrescine) in Sea Fish Dr. Sanaullah Iqbal
by Faseeha Farooqi (2012-VA-541) | Dr. Muhammad Nasir | Prof. Dr. M. Athar khan.
Material type: ; Literary form:
not fiction
Dissertation note: Biogenic amines (BAs) which are the nitrogenous compounds with lower molecular weight and they are formed by the decarboxylation of free amino acids by bacterial activity in food products during fermentation process and storage of the food (Sorungbe, 2005). Diet having high concentration of these complexes are the main source of biogenic amines in body.The most communal biogenic amines which are identified in food are Putrescine, tyramine, histamine and cadaverine. Uncontrolled microbial enzymatic activity of bacteria causes them to accumulate in food (Adam et al. 1999).
Foods having high quantity of biogenic amines includes fermented vegetables, meat products, fish products, juices, dairy productand alcoholic beverages e-g wine and beer. When biogenic amine histamine is ingested it first reaches to the gastrointestinal tractwhere, it binds to some specific receptors if the detoxification system is not capable to remove it (Jarisch, 2004).
Biogenic amines in bodyinvolves inmany important physiological functions, if their level is high in the body then it signify a direct danger to human well-being. There are some drugs e-g ethanol inhibit enzymes of biogenic amines catabolic pathways (Bodmeret al. 1999).
Presence of biogenic amines can be bad indicator for meat it shows the presence of bacteria in meat which caused spoilage of meat (Miceal et al. 2007).
More quantities of biogenic amines in processed, cooked and fresh foodstuffs can be associated to low sterile quality meat. Histamine which is most common biogenic amine acts as vasodilator and neurotransmitter on cardiovascular system and on central nervous. If histamineexceeds to certain level in body then it causes vomiting,diarrhea,headaches, cramps,stomachache, nausea, migraineand hypotension (Moreira et al. 2008). Histamine stimulatesthe smooth muscles of the gastrointestinal tract and uterus, often increases the exoneration of acid release from gastric mucosa, diarrhea, stomach ache and cramps. Another signs ofhistaminases causes the allergic reactions to the skin which includes pruritus flush and urticarial. Reduction of biogenic aminesin food industry is amission for the future (Prithwiraj et al. 2010).
Improvement of diagnostic standard approaches for identification of biogenic amines in food product is good attention not only because of their toxicity level, on the other hand it can also be used as food quality indicators, consenting biogenic amine checking from raw materials to the ready to eat food. In corresponding, techniques for the identification of biogenic amines generating bacteria been established to access risk of biogenic amines formation in food content and to avoid their accumulation in eatable stuff. Safety of food is the main obligation that should be fulfilled during manufacturing process. While high intensity of biogenic amines are associated to customer health and their deliberations in food still not sufficiently standardized by governing organizations (Lehane et al. 2000). At present time, there are certainly no common regulations which defines the parameters and limits of biogenic amine tolerance in food products. Biogenic amine levels are irregularly distributed in food product on the other hand more control must be used on fermented food products of local source or got with traditional procedures (Paulsen et al. 2007).
It is assumed that the existence of biogenic foodborne harming or poisoning is generally underestimated for the reason that of misdiagnosis and under reporting. We believes that the scientific diffusion of the tools that identify or determine the development of biogenic amines in food and the hazards related to their consumption might contribute to increase the alertness and awareness of hands involved which encourages the more responsible portion and consumption of better protection and quality of food (Patange et al. 2005).
